Yip I got the extreme black one with the green led fans.
Ok on the up side:
REALLY sturdy case, solid & made of good materials.
Comes with 5 fans, all of which light up green.
Removable mobo tray for me is better than sex

Cleaning is a pleasure because you can open up the side where the mobo is and have access to the mobo easily.
Cool tool box that slides in at the bottom of the case to keep screws etc.
HDD bay slides out to the side for easy access to HDD's
On the down side:
Fans could be a little quieter which might bother you if you care about that much. You can always replace them. I have actually disconnected one of them.
Green LED's may be a bit overkill for you, I dig it

Heavy, if you travel with your box a lot it may not be ideal.
And thats about it hey, so the pros out weight the cons.
All in all it is a great case. For me the build quality really impressed me, you feel you get your money's worth.
The sirius also looks really really sweet. I love the monitors in the front.
The only thing I am not crazy about on that case is the twirly design on the side panel, but its not that bad, would get used to it.
Either way they both good cases.
